NUMERICAL SIMULATION OF GAS DYNAMICS OF IN-FURNACE CHAMBER

This article discusses dynamics of gas phase in basic furnaces applied upon the melting stage of sulfide polymetallic ores and concentrated nonferrous metals containing copper and nickel. The patterns of gas flow in flash smelting furnace, the Vanyukov furnace, in the Ausmelt process were determined by numerical simulation in nonstationary mode. The obtained solutions of the Navier-Stokes equations are in good agreement with practical operation of these facilities. This article also describes numerical simulation of an alternative jet rotation apparatus which allows to increase significantly specific blasting load with formation of cyclone effect in gas phase, which suppresses dust entrainment and decreases load on dust collectors.
